概括
在内动脉瘤的流量转移器 (FD) 中添加线圈并没有降低延迟破裂率. 卷轴可能会导致更糟糕的结果,这表明它缺乏与FDs结合的破裂预防的有效性.
科学领域:
- 神经外科 神经外科
- 干预性神经辐射学
- 脑血管疾病 脑血管疾病
背景情况:
- 延迟破裂 (DR) 是用于内动脉瘤的流量转移器 (FD) 治疗后的一种风险.
- 卷轴有时与FD一起用于防止破裂,但其有效性尚未得到充分证实.
研究的目的:
- 评估辅助卷轴对防止用FDs治疗的内动脉瘤延迟破裂的影响.
- 评估日本目前使用FD卷轴的做法.
主要方法:
- 在124所日本机构中进行了回顾性调查.
- 收集了5527名用FD治疗的患者的数据,分析了5211例动脉瘤.
- 将FD单独和FD与卷轴组之间的结果进行比较.
主要成果:
- 在单独的FD和带有卷轴组的FD中,延迟破裂率为0.7% (36/5,527 vs 9/1,286).
- 用FD和卷积治疗的动脉瘤往往是巨大的,位于上状细分或状内动脉 (ICA).
- 在使用卷轴组的FD中,结果较差,其中67%的人经历了严重的残疾 (mRS 6).
结论:
- 附加线圈似乎无法防止在流转器处理后延迟破裂.
- 用卷轴治疗的动脉瘤可能会被选择为更大的尺寸或更高的风险,这可能解释了更糟糕的结果.
- 常规的松散卷轴在破裂预防方面没有被证明的好处,可能是由于选择偏差.

Underflow Gates
27
Underflow gates are vital for controlling water flow in irrigation canals. The three main types of underflow gates — vertical, radial, and drum gates — serve different purposes while ensuring effective flow management. Vertical gates move up and down, generating a free-flowing water jet; radial gates pivot to regulate the flow; and drum gates rotate for precise adjustments. The flow through these gates is influenced by downstream conditions, resulting in free or drowned outflow.Free and...

Rapidly Varying Flow
32
Rapidly varying flow (RVF) in open channels is characterized by abrupt changes in flow depth over a short distance, with the rate of depth change relative to distance often approaching unity. These flows are inherently complex due to their transient and multi-dimensional nature, making exact analysis difficult. However, approximate solutions using simplified models provide valuable insights into their behavior.Key Features of Rapidly Varying FlowRVF is commonly observed in scenarios involving...

Surgical interventions for inflammatory bowel disease (IBD), which includes ulcerative colitis and Crohn's disease, are essential in managing symptoms and addressing complications. The selection of surgical procedures is contingent upon the specific conditions and complications that stem from these illnesses.
